c2hs: C->Haskell FFI tool that gives some cross-language type safety

[ development, gpl, program ] [ Propose Tags ] [ Report a vulnerability ]

C->Haskell assists in the development of Haskell bindings to C libraries. It extracts interface information from C header files and generates Haskell code with foreign imports and marshaling. Unlike writing foreign imports by hand (or using hsc2hs), this ensures that C functions are imported with the correct Haskell types.

Readme for c2hs-0.28.8

[back to package description] 
`c2hs` is a interfacing tool that eases Haskell access to C libraries.
The tool gets information about the C data type definitions and
function signatures by analysing the C header files of the library.
It uses this information to compute the missing details in the
template of a Haskell module &mdash; called the binding file &mdash;
that implements a Haskell binding to the C library.  Hooks embedded in
the binding file signal where, which, and how C objects are accessed
from Haskell.  The Haskell code in the binding file determines Haskell
types signatures and marshaling details.

Further information is on the
[wiki](https://github.com/haskell/c2hs/wiki/Home).  Also see the
[user guide](https://github.com/haskell/c2hs/wiki/User-Guide) (also
available in the `doc` directory of the repository).
